Formulated by Legor® Group, this basic yellow casting alloy delivers bright, oxidation-free castings with a light yellow color in 18-karat gold and exceptional fluidity. Additives generally include lower amounts of silver and higher amounts of zinc and silicon. A master alloy casting grain is a pre-formulated mix of base-metal elements; add the appropriate amount of precious metal grain to the master alloy to create the casting alloy you need.
